If you should have any questions, please state the equipment type and serial
number!

8.1 Error messages

Error massages are indicated by the red LED „Fault" located on the panel and the fault relay is re-
leased (see 5.2.1). In addition the metal alarm relay of the conventional design is released, too.

8.1.1 Interface to evaluation unit interrupted

This message appears if the data interchange between evaluation board (see spare parts view 9.1
No.4) and controller unit is interrupted.
Possible causes
Data communication cable between evaluation elec-
tronics board and control electronics board is broken.
Interface module broken.

8.1.2 Transmitter or receiver faulty

This message appears, if either the transmitter voltage or the receiver voltage is very low.
Possible causes
Broken transmitter connecting cable
Broken search coil

8.1.3 Receiver voltage too high

This message appears if the RF voltage at the receiver is too high.
Possible causes
Big metal part (e.g. aluminum ladder, screwdriver,
hammer, bracelets) directly beside or in the detection
coil.
Improper installation of the search coil

8.1.4 Battery voltage too low

Possible causes
The buffer battery (see 3.2.2) located on the controller
board is flat.
8.1.5 24V switching output overload
Possible causes
Short circuit at the connection cable to magnetic valve
of the reject unit
Remedy
Check cable and connectors with ohmmeter;
Replace cable, if necessary
Replace evaluation electronics board and control
electronics board
Remedy
Connector (3) „transmitter" at the evaluation board
(see 3.2.3), switch off and on. If still failure, replace
evaluation board and/ or transmitter cable.
Check search coil for mechanical damage;
Replace the search coil, if necessary
Remedy
Check the detector head and the surrounding. Some-
times metal parts can be found inside or underneath
the belt.
See Op. Man Detection coil: „Installation
If detector head DLS is used, check on loose centering
pins or fastening bolts.
Remedy
Contact TecTronix Systems service
Remedy
•
Check cable and plug of short circuit with ohmme-
ter (if necessary replace cable)
•
Check the resistance of the magnetic valve, which
is 320...340 Ω ( or 100...140 Ω for pusher applica-
tion).
